Check Digit Verification of cas no

The CAS Registry Mumber 111400-53-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,4,0 and 0 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 111400-53:
(8*1)+(7*1)+(6*1)+(5*4)+(4*0)+(3*0)+(2*5)+(1*3)=54
54 % 10 = 4
So 111400-53-4 is a valid CAS Registry Number.

THERMAL REARRANGEMENT OF 3H-PYRROLES BY COMPETITIVE -SIGMATROPIC SHIFTS, AND THE REVERSIBILITY OF THE 3H- TO 2H-PYRROLE INTERCONVERSION

Chiu, Pak-Kan,Sammes, Michael P.

, p. 2775 - 2778 (2007/10/02)

3-Ethoxycarbonyl-3H-pyrroles are converted via thermal -ester shifts to the isomeric 1H-pyrrole-4- and N-esters.Isolable intermediate 2H-pyrroles are converted into the same products, and also into the 3H-pyroles, demonstrating conclusively the reversibility of the 3H- to 2H-pyrrole interconversion.
